AD9985AKSTZ-110

Specialized Overview

The AD9985AKSTZ-110 is an 8-bit, 140 MSPS analog interface IC designed for flat panel displays. It features a maximum conversion rate of 110 MSPS and a 300 MHz analog bandwidth. The device operates on a single 3.3 V supply with typical power dissipation of 500 mW. It includes three ADCs, a PLL clock generator, and full sync processing. The component is housed in an 80-lead LQFP package and supports an operating temperature range from -40°C to +85°C.

Specialized Feature Summary

• Integrated triple ADC with internal reference and programmable gain control
• On-chip PLL generates pixel clock from Hsync input with coast mode support
• Full sync processing including composite sync and sync-on-green handling
• Automated clamping level adjustment for DC restoration

Specialized Applications

• RGB graphics processing
• LCD monitors and projectors
• Plasma display panels
• Scan converters
• Digital TV

Specialized Procurement Notes

Verify the specific suffix '110' against the manufacturer's current ordering guide to confirm the 110 MSPS speed grade. Check for End-of-Life status or Last Time Buy notifications as this component may be discontinued. Ensure ESD precautions are followed during handling due to the CMOS process technology.

Specialized Selection Notes

Select this part when capturing RGB signals up to SXGA resolution at 75 Hz. Verify that the system requires a 3.3 V logic interface and single-supply operation. Consider the 80-lead LQFP footprint for PCB layout constraints. Confirm compatibility with downstream digital logic voltage levels if lower than 3.3 V is required.

Specialized Part Context

This component belongs to the AD9985A series of display interface ICs. It serves as a bridge between analog RGB sources and digital display controllers. The device integrates signal conditioning, digitization, and clock generation into a single monolithic solution, simplifying the design of flat-panel display systems.
